Hello and thanks everybody for your answers.
Following Denial answer: what I understand then is that my error is in thinking that the hypotheses of thin plates do not have to be verified on a single element but on the overall structure that the mesh is representing. Correct?
That is so obvious...
Hi, I just started a new job where we perform linear analyses on steel structures of cargo ships. Near doors and windows we need to increase the mesh density so to capture local stresses. Currently the accepted maximum thickness/side length ratio is 1x1, meaning that we often have 45mm plates...
